Also, for anyone that reads this in the future, the tune has B9021 cax loaded, and the suspect injectors still misfire with B4003, and B4004 set to .015198.

Thanks. No harm in trying the injectors you suggest. PM sent.
Where do you purchase injectors if you need more flow?
Ive used these in several turbo trucks over the years.

Turbo - The 3412's and 5-6psi is a great place to start and the FIC 72's will be perfect if I turn it up.
Thanks for your help.
To close this out, the injectors were the culprit - couldn't handle the low pulse widths. Clues were that the misfires were only at idle and light throttle and, that the misfires followed the injectors. Only 3 out of the 8 injectors had the problem.
